Answers

Answer 1
Answer:

Sandy collects 2 shells at a time

Shawn collects 4 shells at a time

Sonya collects 10 shells at a time.

Find the lowest possible number that they all have similar. Look at their factors

2 x 10 = 20

4 x 5 = 20

10 x 2 = 20

20 is the lowest number

hope this helps
Answer 2
Answer: seems that you are trying to say that:sandy collects 2 shells at a time (so she doesn't collect 1 or 3 at a time)shawn collects 4 shells at a timesonya collects 10 shells at a time

this is a problem to find the least common multipleone way is to list all the number of shells they can collectthe number of shells sandy can collect is 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28...
the number of shells shawn can collect is 4, 8, 12, 16, 20, 24, 28, 32...
the number of shells sonya can collect is 10, 20, 30, 40, 50...

when is the first common number?
it is 20so answer is 20 shells is the least number they must collect



the way to do it with math is thiswhat is least common mulitpule of 2,4, and 10?factor them2=24=2*210=2*5LCM contains the factors of eachso LCM=2*2*5=4*5=20LCM=20
so least number of shells needed to be collected is 20

If a cone-shaped vase can hold 45 cubic centimeters of water and has a radius of 2 centimeters, what is the height of the vase? Use 3.14 for pi. Round your answer to the nearest hundredth.

Answers

Answer:

3.58

Step-by-step explanation:

45cm3= 2 squared x height x 3.14

So you take 45 and divide it by 2 squared which is 4 and 3.14. Then you would get 3.582 and round it to 3.58

Answer:

13.14

Step-by-step explanation:

v= 1/3 pi r^2 h

45 = 1/3 (3.14) (4) h

45 = 1/3 (12.56) h

45 = 1/3 12.56/ 4 = 4 h/4

h = 3.14

45 = 1/3 (12.56)  (3.14)

45 = 1/3 (39.44)

45 = 39.44/3 = 13.14

A fruit company delivers its fruit in two types of boxes:large and small. A delivery of 9 large boxes and 7 small boxes has a total weight of 216 kilograms. A delivery of 3 large boxes and 5 small boxes has a total weight of 90 kilograms. How much does each type of boxes weigh?

Answers

Answer:

The weight of the larger box is 18.75 kg

The weight of the small box is 6.75 kg

Step-by-step explanation:

Let

x -----> the weight of large box

y ----> the weight of small box

we know that

The system of equations is equal to

9x+7y=216 -----> equation A

3x+5y=90 -----> equation B

Solve the system of equations by graphing

Remember that the solution is the intersection point both graphs

using a graphing tool

The solution is the point (18.75,6.75)

therefore

The weight of the larger box is 18.75 kg

The weight of the small box is 6.75 kg

Ashton is saving money to buy a new bike. he needs $120 but has only saved 60% so far. How much more money does ashton need to but a bike?

Answers

The best thing to find out how much he has already saved.
As you're looking for 60%, the best thing to do is to find 10% and then multiply accordingly.
To find ten percent, divide 120 by 10.
therefore, 10% is $12.
As you're looking for 60%, you need to multiply this by 6.
12*6= 72.
So far, Ashton has saved $72, and you're looking for what is left, so you need to subtract this from 120.
120-72= 48
therefore, Ashton needs to save $48 more to buy the bike.
Hope this helps :)
